E425H Firewall Rules

Hi everybody:

Is it possible to block all Internet traffic in the E425H, except one service, like WhatsApp? I want to prevent all the users in an SSID to access anything but WhatsApp.


That would probably not be a good idea as WhatsApp uses TCP 443 (HTTPS) to pass the majority of the connection traffic but it also uses TCP 80 (HTTP).

Yes it may be possible but will require some work of trial and experiment.
See here, you have a full description of what addresses Whatsapp uses

Thanks guys. I first need to learn how to properly set the firewall rules to start experimenting.

Done. That this is no more complicated than screwing in a light bulb :slight_smile:
